' parts:

To all whom it may cow/cem:

Be it known that I, ROBERT FULTON CoM- sTooK, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented cer-` tain new and useful Improvements in Batter Pumps, of which the following is a specification. v

' My said invention relates to a batter pump intended primarily for use in making ice cream cones and it is` an object of the invention to provide a pump of this character which shall act in a very direct manner so as to distribute batter taken from a reservoir to the molds of the machine with a minimum of contact with other parts of the mechanism. Due to this fact and also to the fact that the parts are operated very accurately it is possible to reduce to a minimum the waste of batter in the mold.

Referring to the accompanying drawings which are made a part hereof and on which similar reference characters indicate similar Figure 1 is a broken away;

Figure 2 a section on the line 2*2 of Figure l;

Figure 3 a longitudinal section; and

Figure 4 a transverse section on line 4 4 of Figure 3 showing certain parts in the opposite position from that of Figure 2.

In the drawings reference character 10 indicates the base of the machine said base having a conduit l1 underneath leading from a pipe 12 connected to a reservoir of any convenient form for holding the batter to be made into ice cream cones. A plug 13 closes the outer end of said passage and provides means whereby the same may be readily accessible as for cleaning `and the like. A plurality of branch passages 14 Vextend laterally and then upward from the `main passage 11. A similar number of passages 15 extend downward through the base, said passages communicating in any desirable or conventional manner with the molds in which are formed the cones for the reception of ice cream. Above the passages referred toa block 16 is slidably mounted on the base said block having at its lower end an oppositely dovetailed projection 17 extending under corresponding overhanging parts on the base 10.

For convenience in entering and removing plan of my device partlybefore the block a triangular shim 18 is located between one of said dovetailed parts and one of over-hanging parts on the base. shim also serves to-compensate for wear between the engaging sides of-the block 16 and the base by means ofset screws 19 arranged to bear against the outer side of the shim, these set screws-being provided with lock nuts 20 for securing them in place. Obviously a series of shims may be provided instead of the single one illustrated without changing theV invention.

rlhe blockhas a series of cylinders 21 corresponding in number to the branch passages 14and 15 Awhich act respectively as inlet and outlet passages for the cylinders. Preferably the cylinders have linings indicated in section at 22 in Figures 3 and 4 but this is not essential. rThel contacting surfaces of theblock 16 and base 10 vare lubricated by means of reservoirs 23 at the ends of the block said reservoirs being provided` with wicks 24 leading down to such surfaces. f Within the cylinders are provided pistons 25 attached by means of connecting rods 26 to rockarms 27 on a rock-shaft 28 journaled in bearings on the block 16. An. arm 29 near one end of the rockshaft extends upward and has a ball-shapedv extremity engaging in a slot in a bent 'lever 30 pivoted at 31. The movement of the lever in one direction is limited by a set screw 32 provided with a lock nut 33.

A rod 34 is connected to the other arm of the bent lever by a slidable pin-and-slot connection and a screw 35 is mountedin a threaded opening in a boss on the rod said screw being locked in place by a nut 36. Adjustment of the 'screw serves to vary the stroke of the piston, and therefore the charge of batter in each cylinder.

In the operation of my device the block is reciprocated by any suitable means with a throw moving it from the position illustrated in Figure 3 to a position in which the cy inders are directly above the outlet ports 15. When the cylinders are in the position of Figure 3 batter is drawn into them by the upward movement of the pistons and this batter is forced out through the outlet ports in the other position due tothe faetthat the pin 30 on the lever 30 which moves with the block reaches the end of the slot in rod 34 the block has attained the endA of its Saidy movement in that direction (i. e, to the right) whereupon the bent lever swings about its pivot 31 thereby rocking the arm 29, the shaft' 28, and the arms 27 to force the pistons down in their cylinders as thev cylinders assume a position over the outlet ports l5. The batter, in the cylinders 1s lejected with a sudden spurt near the end of of Figure l thereby rocking the arm 29,'

shaft 28, and arms 2? t0 lift the pistons and quickly fill the cylinders With batter Whereupon the operation may be repeated.

lt will be obvious to those skilled in the art that my device may be changed in various Ways Without departingl from the spirit of the invention and therefore l do not limit myself to the specific embodiment shown in the dr Wings and described in the specification but only as indicated in the appended claims. Y

Having thus fully described my said invention What l claim is: Y

l. A batter pump comprising a base, a cylinder block slidable onsaid base, inlet and outlet passages arranged to communicate with' the block at different extremities of its movement, a piston in each cylinder, a shaft journaled on said block, rock arms on said shaftv connected to said pistons, a bent lever having rocking connection With an arm on said shaft and a lost motion connection between said bent lever and the fixed frame ofthe machine whereby the pistons are operated at the extremities of movement of the block, substantially as set forth.

2. A batter pump comprisinga base, a cylinder block slidable on said base, inlet and outlet passages arranged to communicate with the block at different extremities of its movement, a piston in each cylinder, a shaft journaled on said block, rock arms on said shaft connected to said pistons, a bent lever having rocking connection With an arm on said shaft, a lost motion connection between said bent lever and the fixed frame of the machine whereby the pistons are operated atvthe extremities of movement of the block, and means for adjusting tion connection t0 vary the stroke of the pistons, substantially as set forth.

3. A batter pump comprising` a base having a series of inlet and outlet passages for batter, a rcylinder block mounted to reciprocate on saidj base and having a series of cylinders each adapted to register with one of said inlet and outlet passages alternately, a piston in each cylinder, a piston rod connected to each piston, arockshaft journaled longitudinally of saidl cylinder block and relatively long rock arms fixed to said shaft and Vpivotally connected Vto said piston rods, and means having movement substantially parallel to said rockshaft for operating the same, substantially as set forth. Y

ln Witness whereof, l have hereunto set my hand and seal at Louisville, Kentucky, this 24th day of J une, A. D. nineteen hundred and twenty-four.
